Whether or not there’s PR leverage to be had in prematurely announcing your submission to Apple’s App Store approval process remains to be seen, but it does give us a sneak-peak as to what’s (hopefully) coming down the pipe. Sling Media have tipped us on their latest iPhone and iPod touch app, SlingPlayer Mobile 1.1, which now includes full 16:9 widescreen support (i.e. that takes up the whole width of the display) and improved DISH Network integration.

Whereas in the first-gen version of the app DISH Network users had to navigate from a streamed image of the TV UI, Sling have now created a native browser for trawling the service. It actually offers more functionality than a standard DISH Network box might give you when you’re sat in front of the TV, too, as there’s search and filtering on offer.

While AT&T and Apple have still not changed their tune on 3G streaming – and the version of SlingPlayer Mobile submitted for inclusion in the US App Store only supports it over WiFi – the company have submitted a second version for international use that enables 3G access. Sling Media tell us they’ve “not heard back” on whether that second app will be approved or not.
